| Earlier this fall there had been some discussion regarding topdress applications of NH3 to winter wheat. http://talk.newagtalk.com/forums/thread-view.asp?tid=75309&posts=10...
We "tried" 50 acres last week to see just how much damage it would do. Our applicator is set up on 20" spacing using Wako NTO openers. We were running at a 10 degree angle to the direction the wheat was planted and solid conditions were still a little wet. This wheat has been grazed, pre-plant N was applied with the same machine and the wheat was sown with an 1890 Deere airdrill on 10" spacing. My initial observations are that the wheat needs to be of fairly good size and well rooted in soil that undisturbed or re compacted by rain. Soil density, moisture & and the amount of residue greatly impact the level of soil disturbance. Heavy residue significantly reduced the amount of soil blow out caused by the coulter. Compacted soil near the gate with little residue did not look good when we were finished, and I suspect wheat sown into conventinally tilled soil would not stand a chance unless it was heavilty tillered and of good size.
